I am waiting to level up for one because these dudes are hard and even onn the testrealm i cant do it with those hench mens and i would like it to be a little eaier just like 10% :?
The nice thing about Grizzleheim is you can do it whenever. You don't have to go do it right at level 20, you can wait until you've learned another spell and come back when it's a little easier. Or you can wait and do it all after Mooshu -- it's up to you.
